ROAD PLANING AND FINISHIN G MACHINE.

To all whom it may concern: 1

Be it known that I, OR'IUS E. MoA'rs, a

citizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and useful-Imrovements in Road Planing and Finishing achines,'ofwhich the followlngMy invention relates to road making ma chines, and has for its object toprovide a new and improved machinevwhich will be well adapted to smooth,crown and rolla 7 road so as to leave it in a finished condition. Tothis end, it contemplates a machine providedwith extensible scraperswhich project laterally from. both sides of the machine frame and are"adjustable to any desired angle, and also to be folded or withdrawnunder the frame of the [machine so that the -machine may readily bemoved-from place to place. It also contemplates the provision of ascarifier cooperating with such scrapers to break up or loosen the hardcenter of the road and enable the scrapers to properly level" and smoothit. It further contemplates the provision'of a roller adapted to rollthe road after the scrapers have passed over it 7 crowning roller, partsofthe main and at the same time give it theproper crown. In connectionwith thesegeneric features my invention also includes mechanism by whichthe various adjustmentsof the scrapers, scarifier and roller may .be

efficiently accomplished, all of which is here-' i inafter described. IIn the accompanying drawings- I Figure l'is a side elevationof myimproved machine; i

the frame in which it is :erably made up of I-beam material shapedconsiderably narrower than the rear end of the machine. The intermediateportion of the main frame tapers toward the front, as

' illustrated. It will be understood, of course,

that the shape of the frame may be varied as convenience may suggest.The rear portion of the main frame is supported upon wheels 14 mountedon spindles carried by an axle. 15, which, as best shown in Fig. 7,extends over the main frame and is'fixedly secured\thereto in anysuitable way. V The frontnp'ortion of the frameis supported by wheels 16mounted on an axle 17, which as best shown in F ig.' 1, carries a lowerfifth wheel member 18. A tonguej19 is connected 1 .with the lower'fift'hwheel member by means of tongue-irons 20, in the usual way, so that themachine may be steered-by swinging the tongue and thereby swinging ,thefront axle. The front end. of the main frame 13 is mounted on a bolster21, which connects with, the upper member 22 of the fifth the twomembers of the -fifth wheel being pivotally connected together by aking-bolt, 23 passmg through bars" 2425 connected, respectively, withthe lower'and upper members of the fifth wheel. 126 27 indicatesupplemental bolsters between the forward portion of the main frame andthe upp member 22 of the fifth wheel; and 28/indiwheel,

rates a draft-bar secured between the rear end of the bolster 27 and theupper member 22 of the fifth wheel, the king-bolt 23 extending throughthe forward end of said draft-bar. 29 indicates an arched bar which issecured on the forward endof the main frame, its end portions extendingdownward and outward therefrom and terminating, as

shown in Fig. 3, in supporting arms 30 in the form of hooks, the purposeof which is to support the forward ends of the lateral scrapers whenthey are folded, as will be hereinafter described.

At the rear ofthe machine and approximately in line with the rearwheels, is a crowning roller 31, which is disposed transversely of themachine so as to overlie the central portion of the road when themachine is in position to operate. The roller 31 is made up of a numberof sections 31*, which are mounted on a shaft 32, as best shown in Fig.7. These rollers are tapered and are so proportioneTD and mounted on theshaft 32 that together they form a roller having a concave surface whichconforms to the crown to be imposed upon the road. Obviously, bychanging the sections of this roller, the curvature of the roller as awhole may be varied, consequently varying the curvature of the crown ofthe road produced by the use thereof. The end portions of the rollershaft 32 are secured to a frame 33 pivotally connected, by forwardly-projecting draft-links 34 shown in Figs. 1 and 8, with the main frame13, the pivots of said draft-links being shown at 35 in Fig. 1. Byconnecting the roller with the main frame at a point forward of its ownaxis, the draft is properly applied thereto, and the draft-links 34being pivoted the roller can rise and fall. When the machine is in useit is'oftentimes desirable to apply as much pressure as possible to theroller, and to this end, I provide means by which the entire weight ofthe rear portion of the machine may be thrown. upon the rollersupporting frame, and through it be applied to the roller. Theconstruction by which this is accomplished is best shown in Figs.- 7 and8. As therein shown, the rear axle 15 is provided with brackets 36secured to the vertical portions. thereof, preferably by clamps 37.These brackets are provided with vertically-disposed sleeves 38internally screw-threaded to receive the threaded portions of rods 39having hand-wheels 40.

The sleeves 38 overlie the side portions of the roller frame 33 over thepoints where the endsof the roller shaft 32 are secured,

so that by screwing down the rods 39, their lower ends may be forceddown upon the side members of the roller frame 33, thereby acting aslifting-jacks to raise the rear portion of the main frame and support itupon the roller supporting frame. By this means, great pressure may beapplied to the .roller, and its efficiency in crowning the road bethereby greatly increased. In the be, thereby construction illustrated,the ends of the rods 39 do not bearhdirectly upon the frame 33 but uponshort angle-plates 41 whlch are fitted upon the frame 33 under the lowerends of the rod 39 and over the rear end portions of the draft-bars34,-these parts being bolted, or otherwise suitably secured, together.The plates 41 may be easily removed and replaced when desired. For thepurpose of steadying the roller 31 and holding it against endwisemovement, the brackets 34 are provided with downwardly-projecting arms42 opposite the ends of the roller shaft 32 and in position to bearagainst the vertical portions of the angleplates 41, as shown in Fig. 7.Thus, when the roller frame moves vertically with reference to themachine frame, or the machine frame moves vertically with reference tothe roller frame, the angle-plates 41 slide against the inner surfacesof the arms 42,

endwise movement. When desired, the roller may be raised'out ofoperative position, this being accomplished by means of chains 43 whichare secured to the rear portion of the roller supporting frame 33, asshown in Figs. 1 and 8, and are adapted to be wound upon drums 44carried by a shaft 45 mounted transversely upon the rear portion of themain frame 13, as shown in Fig. This shaft is provided with a worm wheel46 shown in Fig. 3, which meshes with a worm 47, shown in Fig. 1,mounted on a vertical rod 48 having a hand-wheel 49. By rotating thehand-wheel 49 the shaft may be rotated, thereby winding up the chains 43upon their respective drums, or ui'lwinding them, as the case mayraising or lowering the crowning roller. Of course, when theroller is tobe raised, the pressure rods 39 must be moved up sufficiently to p mitthe roller to be lifted. 50 indicates sc apers which bear upon thesurfaces of the several roller sections, said scrapers beingpivoted uponthe roller frame 33, as shown at 51 in Fig. 8, and having arms 52carrying weights 53 by which .the scrapers are yieldingly pressedagainst the surfaces of the roller sections. In advance of the crowningroller, the machine is provided with means for preparing the road forthe final rolling operation. This mechanism consists principally of twocompound scrapers adapted to be projected laterally at opposite sides ofthe machine at and the roller is steadied and held against a variety ofangles'and provided with means v is pivotally secured a forkedbracket-57 by ascrapers, and 56 indicates the scarifier; The

inner members 54 of the lateral scrapers are preferably considerablyshorter than the outer members 55 thereof, and the members 5 of eachscraper are pivotally connected topivot-bolt 58, sothat said bracket mayrock I about a horizontal axis. The bracket 57 embraces an I-beam 54which forms a part of the scraper member 54 and is pivotally con nectedtherewith by a vertical pivot-b01559,

pivot 59, and at their uncture they may also sal joint'or coupling.

as shown. Thus, the two members 5455 of each lateral scraper may swingin a horizontal plane to different angular positions with relation toeach other, turning about the be swung vertically to different angularpositions with relation'to each other, turningabout the pivot-bolt 58.In other words, they are connected by a substantially unlver- The rearend portlons of the'members 54 of the lateral scrapers are held inoperative position and adjusted vertically by means of a hand-lever 60mounted on the mam frame and provided with the usual segment 61and latch62 for looking it indifferent positions.

The lever 60, as best shown in Fig. 12, is in the form of a bell-crank,its lower. arm 60 projecting forward and being connected by a bar 63with an arch 64, the ends of which 121.18 connected with the rearend-portions of the scraper members 54, as best shown in Figs. 1 and 4.Thus, by operating the lever 60 the height of the rear endsof thescraper members 54' may be adjusted as desired.

The forward end portions of said scraper members 54 are held in positionby bars "65,

the outer or rear ends of which are connected to the scraper members 54by bolts 66, as

best shown in Fig. 6. As therein shown, the

bars 65, which are preferably double, are provided at their outer endswith stirrups 67 which rest upon ears 68 projecting from-the.

I-beams 54*, the bolts 66 passing through the members of the bars 65,through the st1r-,

extending draft-bar 70, which is also an,

rups 67, the cars 68, and through corresponding ears 69 secured to thelower flange of the I-beams '54. The forward or inner end of each bar 65is secured to a longitudinally- I-beam, and issupported upon and securedto a cross-brace 7 0 in the mannershown in Figs. 2 and 4. As showninFig. 2, two bars 71-72, which together form a double-ended yoke, aresecured upon the draft-bar 70 transversely/ of the machine, and the endsof the bars are secured'to saidyoke by pins 73. The scraper members 54may be vertically adjusted-by means-of rock-shafts shown in Fig. 9.

and extending longitudinally thereof, as

shown in. Figs. 1 and 3. At their forward ends said rock-shafts areprovided with crank-arms 75,0.onnectdby rods 76 with the I forward endportions of the scraper members 54. The rear ends of the rock-shafts 74-are provided. with worm-wheels 77 which v are operated by worms 78'shown in Fig. 3,

said worms being mounted on shafts 79 pro- Vided with hand-wheels 80.Thus, by ro tating the hand-wheels 80, the operator may adjust theforward ends of the scraper members 54 vertically, as desired. Theadjust:

ment of the two scraper members 54 may be made simultaneously orseparately so faras the-front ends thereof'are concerned, but thelrrearends being connected to the lever 60 are always moved together whensaid lever is operated. I I a It will be apparent that the rear or innerend portions of the scraper members 55, being. connected with theforward end portions of the scraper members 54, are also verticallyadjusted by means of the handwheels 80. The'outer portions of saidlateral scraper members 55 are vertically adjusted.

by means of chains, or other flexible connect'ions, 81, which areoperated by two-- cranesmounted on the main frame of the .machine. Asbest shown in Figs. 3 and 9,

82 indicates an arch, the ends of which are secured to the side membersof the machine frame 13 at a suitable intermediate point,

and 83' indicates a cross-beam which extends across the mainframe 13opposite the lower ends of the arch 82. The arch 82 and loo beam 83 form\the upperand lower bearings Y for the masts 84 of two cranes, saidmastsbeing of I-beam orother suitable construction. They are providedwith upper and lower pivots 8586, respectively, as best of the cranes,which are secured to the masts 84 in any suitable way, their outer endslasses 91 having worm-wheels 92 operated by worms 93 carried'by shafts94 having hand-.

wheels 95, all as shown in- Figs. 9 and 10.

indicates guidesrollersi corresponding scraper member 55 may be raisedor lowered as desired, and the weight of each scraper may be sustainedby its 99 being secured to the outer end portion of the scraper 55 by apivot 103 in substantially the same manner as that described inconnection with the bar 65 and scraper member 54. 104 indicates a link,the outer end of which is connected with the pivot 100, its inner endbeing connected by a pivot 104 with a sliding rack-bar 105' mounted insuitable guides 106 at the under side of the machine frame, as shownin 1. The rack-bar 105 is in mesh with a pinion 107 (see Fig. 4) whichis carried at the lower end of a vertical rod 108 provided with ahand-wheel 109 at its upper end, as shown in Fig. 1. The arrangement ofboth sides of the machine is the same, and the parts are similarlynumbered. Thus, by operating either hand-wheel 109, the'levers 9899 maybe moved either to the position shown in Fig. 4 so as to project thescraper members 55 laterally, or they may be swung back to the positionshown in Fig. 3, thereby folding the scrapers in the manner shown in thelatter figure. When folded, the forward ends of the scraper members 55are lifted into engagement with the hooks 30 so that the scrapers arethen supported by said hooks and are held up out of the way so as not tointerfere with the steering of the machine. The toggle constructiondescribed is very powerful and holds the blades properly in positionwhen in operation, besides making it practicable to shift them underload. 1

The scarifier 56, as shown in Fig. 4, is lo.- cated centrally of themachine in advance of the inner scraper members 54. This scarifier has aV-shaped frame having a number of sharpteeth adapted to engage thesurface of the road and break it up to a moderate depth so as to enablethe scraping devices to level it off properly -to permit of its beingsmoothed by theroller. This scarifier is provided withforwardly-projecting draftbars .110 which at their forward ends areconnected with vertically-slotted plates 111 shown in Figs. 1 and 4. Bymeans of these slots, the plates 111 are connected to a draft-frame 112by a pin 113 which passes through said slots. The forward end of thedraft-frame 112 is connected by a pivot 114, shown in Figs. 1 and 4, tothe draft-bar 28. Thus, the scarifier 56 receives the direct draft. Thescarifier may be vertically adjusted and meanwhile maintained in ahorizontal position by means of bell-crank levers 115-116 mounted onpivots 117-118, respectively, supported by the main frame 13, the upperarms of said levers being con nected by connecting-bars 119 shown inFig. 1. The levers 115-.116 are rocked by means of a screw-threaded rod120, which extends longitudinally ofthe machine, its threaded endpassing through a threaded opening in the upper arm of the lever 116, asshown in Fig. 3, its rear end being fitted in a suitable bearing 121 andprovided with a hand-wheel 122. The lever 115 is connected byconnecting-rods 123 with the slotted plates 111, and the lever 116 isconnected by connecting-rods 124 with the intermediate portion of thescarifier frame. Thus, by operating the hand-wheel 122, the levers115-116 are rocked in unison, and consequently the scarifier may beraised and lowered. its horizontal position being maintained during theoperation. 125 indicates chains connected with the outer portions of thebars and with the main frame 13 at a point in advance of the scrapermembers 54, as shown in Figs. 1 and 3, said chains serving to take thedraft of said scraper members when in operation.

. 126 indicates a center scraper arranged centrally of the machine backof the inner ends of the scraper members 54. as shown in Figs. 3 and 4,said scraper being sup ported by bars 127 pivotally connected at theirforward ends with the outer portions of the scraper members 54, as shownat 128 in Fig. 1. The scraper 126 may be verti-- cally adjusted by alever 129 connected theretoby a rod 130, as shown in Fig. 1. The lever129 is provided with the usual locking segment 131 so that the scraper126 may be locked in its different positions of adjustment.

From the foregoing description, it will be apparent that the lateralscrapers may be projected at opposite sides of the machine so as toextend forward at a greater or less angle with the machine frame, andthat when so projected. by reason of the fact that each lateral scraperis composed of two jointed members, the lateral scrapers may be adjustedto give the surface of the road the desired slope or crown. From time totime these scrapers may be adiusted while the machine is in operation,and when the ma chine is to be moved from place to place, they may befolded under the frame and placed out of the way, to permit the ma chineto be driven through comparatively narrow gates or along narrow lanes.When the machine is in use, the scarifier cuts up t e crown of. the roadin advance of the scrapers and prepares it for the shaving and smoothingoperations. By providing the horizontal lift for the scarifier andapplying central portion of the road is scraped and smoothed by theauxiliary scraper 126, which, as has been described, may also beadjusted vertically to suit the varied conditions of the work. Finally,after the scraping operations, the road is rolled and crowned by thecrowning roller, which, as has been explained, may be pressed down withall the weight of the rear portion of the machine. Either end of thecrowning roller may be adjusted separately'so that its action may becont lled to secure the best results. For transp rtation purposes, theroller may be raised out of contact with the ground, as hasbeendescribed.
